This study also examines brain activity as it relates to depression and treatment. The study includes functional Magnetic Resonance Imaging (fMRI) scans of participants in both conditions before and after they undergo treatment. Participants play a game in the scanner called the Monetary Incentive Delay (MID) task, and they have the opportunity to win money (reward) or to avoid losing money (loss). After they play the MID game, the scan images show certain brain regions that are activated in reward and loss situations. This study looks at how these brain regions relate to treatment response, especially because the goal of BA is to help people enjoy rewards more. The study also compares brain activity between the two treatment groups, as well as changes in brain activity from pre- to post-treatment. This part of the study should provide information about which kinds of people respond to which kinds of treatment.
